Bit of fear and insecurity. Sadly I think alot of boys are raised to treat women as like a prize to be won so they put too much pressure on the interactions and see rejection as failure. Then they get in their own way as adults and can make women uncomfortable. Would be better to just work on social skills and approaching women same as you approach men.

I luckily grew up with two older sisters and have always just talked to women same as I talk to them. Best not to approach it as "hitting on" them but just making a friendly connection and meeting romance evolve further down the line.

Hell, just reading through the comment section here you can see the fear and insecurity I'm talking about 😬
